XML APIs for databases
Blend the power of XML and databases using custom SAX and DOM APIs
Summary
Most Web applications require the presentation of database-generated information. XML, because of its ability to separate content from presentation, is fast becoming an industry standard for data exchange. Most XML tools work with either the SAX or DOM API. This article presents a way to blend the power of a database with the features of XML. It also provides a simple, pure Java implementation of XML APIs for databases that works with any JDBC data source. With this approach, XML tools can treat a database as a virtual XML document.

====
For processing XML documents, most XML tools work with the SAX or DOM API. In this article, we'll look at a way to implement the same APIs directly over a database, enabling XML tools to treat databases as if they were XML documents. That way, we can obviate the need of converting a database.
====

XML APIs for databases: The basics
Because of a database's highly regular data-storage structure, we can map it into data-centric XML documents. For example, we can transform a database table into an XML document with a DTD of the following form:


<!ELEMENT table rows*>
<!ELEMENT rows (column1, column2, ...)>
<!ELEMENT column1 #PCDATA>
<!ELEMENT column2 #PCDATA>

=====

Implementing the SAX API for Databases
To implement the SAX API for Databases, we need to implement a parser that operates on a JDBC data source, iterates over each row and column, and generates appropriate SAX events while iterating. The SAX specification provides the org.xml.sax.InputSource class that models a data source representing a URL or a byte stream. To represent a database, we need a specialized form of it that can represent a table in a database. We therefore implement JDBCInputSource, which extends the org.xml.sax.InputSource class.



and so on and so on.
